Offensive analysis: Devastating when it can hold onto the ball. Twenty lost fumbles and 14 interceptions help the 49ers beat themselves more than once. Nothing need be said about Montana other than arguing if he's best QB in game. Craig now second only to Marcus Allen of Raiders as game's best all-purpose back. Clark (88 consecutive games with a reception) and Rice (10 catches for 241 yards against rival Rams) give club deadly receiving combo. Only problem is aging of line. Tackle Keith Fahnhorst (34 years old) and guard Randy Cross (32) no longer are among best.

Defensive analysis: When 49ers beat Dolphins in Super Bowl, defense relied on trickery more than great depth. Replacements are needed now, especially with pass-rush specialist Fred Dean out of game. LBs all are quick pass defenders who aren't big enough to stuff run. LB Michael Carter made Pro Bowl despite missing four games. And the once-famous secondary no longer has reputation of years past. Still a good defense but never really a great one.

Keys to improvement: More rebuilding is needed than most expect. The talent at skill positions is great, but supporting cast growing old. Right now 49ers have two No. 1s and two No. 2s in next year's draft, indicating Walsh knows what's happening and is preparing to solve problem.

Schedule: Very easy until last month when 49ers tackle Giants on a Monday night, Jets, Patriots and Rams on a Friday night.
